Lime Gauging and Lime Washes over American Clay: More than Just a New Palette
Have you ever noticed how just a couple of new ingredients changes everything exponentially? We’re hard at work introducing a variety of finishes, experimenting, and developing a new palette of options. One of the finish options we work with is American Clay Lime Putty. The focus here is lime gauging and lime wash effects that you can create used in conjunction with the already beautiful American Clay’s line of award-winning earth plasters- Loma, Porcelina, Maritimo and Enjarre. It is a pure high-calcium lime putty mixed with the clay itself (lime gauging) or diluted with water and pigment if desired you create a lime wash by brushing over a previously earth clay troweled wall surfaces. The lime will continue to harden over the days and months ahead creating a harder finish. Benefits include breathability, mold and mildew resistance, and humidity buffering qualities.
The amazing part of it all is that the more we work with the lime effects (along with all the other finishes we have worked with) it continues to teach us something historically, architecturally, and artistically.
This example along the stairwell shows a porcelina clay which is lime gauged. When burnished it highlights the lime and polishes nicely.
This yellow wall has a lime wash. On Loma, Maritimo or Enjarre, the lime wash will be more matte. It can be uniformly applied or more random as in this detail image.

Below is a sample board that shows the Chesapeake Bay Porcelina clay hard troweled with two lime washes applied and burnished. The right white lime wash is pure with no pigment, the left green is the snake river pigment with the lime wash and you can see how quickly the green takes over the underlying clay yet it peaks through. Both create interesting effects. Varying degrees of lime wash with or without pigment can be applied.
